We can understand flow of if statement by using the below diagram. It shows thatcode written inside the if will execute only if the condition is true. 仅在条件为true时,在if内编写的代码才会执行。 If块的数据流图 (Data-flow-diagram of If Block) Example: 例: In this example, we are test...
If you observe the above result, all defined conditions are failing due to that it executed anelseblock of statements and printed the required statement in the console window. This is how we can use theif-else-ifstatement in the c# programming language to execute the block of code or statem...
Swift - If Statement - An if statement consists of a Boolean expression followed by a block of statements. When the boolean expression is true, then only the block of statements will execute. Otherwise, the controls move to the next statement present jus

When all the specified if block conditions are true then the print statement will be executed. public class example { public static void main(String[] args) { int a=10; int b=15; // specified condition inside if statement if (a>9){ ...
To ensure the desired behavior and readability of the code, it is recommended to always use curly braces around the blocks of code associated with theifstatement, even if there is only a single statement. This helps to clearly indicate the scope of the code block and avoids any confusion. ...
If the condition is false, it then executes the statements in the else statement block and then exits the loop. The following diagram shows the flow of the ‘if’ statement.Checking VariablesJust like the ‘if’ statement in Batch Script, the if-else can also be used for checking variables...
The general working mechanism behind the if statement is mentioned below and is also represented in the flow diagram. A simple if statement in C++ is used to check whether a condition is true or false. Then- If the condition is true, the statements inside the if block are executed. ...
